libnl-tiny: Fix for c++ compatibility

g++ compiler issued some errors like "invalid conversion from void* to *struct nl_attr"
when compiling cpp file which calls libnl-tiny functions. (it's OK with gcc)
Also see https://dev.openwrt.org/ticket/7854

Patch from: kentarou matsuyama <matsuyama@thinktube.com>
